The Endurance Athlete’s Guide to VO2max and Lactate Tests
Find out all the dos and don’ts of physiological testing as we break down VO2max and lactate/ramp testing.
Humans aren’t machines—we’re much more complicated. Exercise physiology involves changes in the body from exercise and rest.
From anaerobic threshold to environmental acclimatization, from FTP to PGC-1 alpha, we explore the science of human performance.
Find out all the dos and don’ts of physiological testing as we break down VO2max and lactate/ramp testing.
We explore the physiology of race season—how to find top-end fitness, how long it takes, and the best ways to do it.
Your lactate threshold may not be what you think it is. Coach Trevor Connor explores the true definition of this physiological turn point.
Environmental physiologist Dr. Stephen Cheung addresses whether the amount of fat and carbohydrate used for energy changes with the temperature.
An athlete’s rate of perceived exertion, or RPE, is one of the most underappreciated metrics. For ultra-athletes who are closely in touch with their bodies and minds, working with RPE is an essential component to training and racing.
Your lactate threshold may not be what you think it is. Coach Trevor Connor explores the true definition of this physiological turn point.
How long? How much? How many? Tapering can be a dark art, but we’ve got all your questions answered to help deliver you to your next start line ready to go.
Dr. Stacy Sims gives her advice on how to coach women through all stages of menopause.
We get asked a lot of great—and nerdy—questions via our Fast Talk Labs Forum. Every month we’ll now be taking the best questions and publishing our answers. This month, our in-house physiologist Rob Pickels tackles the topics of altitude training and the impact of body composition on hypothermia.
In this second part of our three-part series, Dr. Stephen Seiler gives us the history of exercise physiology research as well as insights into the inner workings of the academic world.
The concepts of central and peripheral conditioning help explain why an effective training base period leads to speed and durability in the race season.
Medical doctor and elite Zwift team manager Jennifer Real talks with us about indoor training and racing, and how to achieve effective recovery including monitoring sleep and taking Vitamin D.
Dr. Stephen Seiler answers five endurance training questions on heart rate, zones, polarized training, rest, and much more.
Dr. Stephen Seiler shares the “holy trinity” of training feedback in this live presentation at a rowing conference.
Reducing cardiovascular drift and increasing fiber recruitment are key components of sustainability.
Trevor Connor revisits the fundamentals of aerobic versus anaerobic pathways, and helps us understand more advanced principles of interval training.
We answer listener questions on training for long endurance events, cardiac drift, the types of inflammation, and much more.
We sit down with Jumbo-Visma rider George Bennett to better understand how he trains, how you can apply his tips, and how pros have vastly different approaches.
We speak with Hunter Allen and Dr. Andy Coggan, pioneers of the use of power meters in cycling.
